Description

Sphygmomanometer cuff

The present invention relates to a cuff for a sphygmomanometer used for, for example, an upper arm sphygmomanometer, a wrist sphygmomanometer, or the like.

[Correction 23.08.2013 based on Rule 91]
Conventionally, as a cuff for a sphygmomanometer, as disclosed in Japanese Patent Laid-Open No. 10-57323 (Patent Document 1), a cuff band wound around a wrist and provided in the cuff band to compress a wrist artery Some have an air bag to which air is supplied.

In this conventional cuff for a blood pressure monitor, the capacity of the air bag is reduced by making the shape of the air bag in plan view a cross shape. More specifically, the air bag is provided on a wide portion having a wide width (a length in a direction perpendicular to the direction wound around the wrist) and on both sides in the winding direction of the wide portion, and is wider than the wide portion. Has a narrow and narrow part.

[Correction 23.08.2013 based on Rule 91]
Japanese Patent Laid-Open No. 10-57323

In the conventional sphygmomanometer cuff, since the shape of the air bag in plan view is a cross shape, a portion extending in the width direction of the air bag and a portion extending in the winding direction of the air bag intersect each other at right angles. . In other words, the wide part and the narrow part form a right angle.

As a result, when air is supplied to the air bag, stress concentration occurs at the boundary between the wide portion and the narrow portion, so that there is a problem that the right angle portion is easily broken.

Therefore, an object of the present invention is to provide a sphygmomanometer cuff that can reduce the capacity of a fluid bag and can hardly break when a fluid is supplied to the fluid bag.

In order to solve the above problems, the cuff for a blood pressure monitor of the present invention is
A fluid bag supplied with fluid to compress the artery;
A fixing means for fixing the fluid bag to the portion to be measured having the artery,
The fluid bag is
A wide portion disposed on the artery;
It has a narrow part narrower than the wide part connected to the wide part,
The edge of the narrow part connected to the edge of the wide part has a substantially linear shape inclined with respect to the width direction.

Here, the substantially straight line shape includes a straight line shape and a shape in which a part of the straight line (for example, an end) is curved.

According to the above configuration, since the fluid bag has a narrow portion that is narrower than the wide portion, the capacity of the fluid bag can be reduced.

Moreover, since the edge of the narrow part connected to the edge of the wide part has a substantially linear shape inclined with respect to the width direction, the wide part and the narrow part can form an obtuse angle. Therefore, when a fluid is supplied to the fluid bag, stress concentration does not occur at the boundary between the wide portion and the narrow portion, thereby making it difficult to cause tearing.

In the cuff for a blood pressure monitor of one embodiment,
The narrow portion is provided at one end in a direction orthogonal to the width direction of the fluid bag.

According to the above embodiment, by providing the narrow portion at one end portion in the direction orthogonal to the width direction of the fluid bag, the artery can be sufficiently compressed even if the capacity of the fluid bag is reduced.

In the cuff for a blood pressure monitor of one embodiment,
The narrow portion is provided at a central portion in a direction orthogonal to the width direction of the fluid bag.

According to the above embodiment, the capacity of the fluid bag can be further reduced by providing the narrow portion at the center in the direction orthogonal to the width direction of the fluid bag.

In the cuff for a blood pressure monitor of one embodiment,
The fluid bag is provided with a partition that partitions the fluid bag into a plurality of spaces.

According to the above embodiment, since there is a partition portion that partitions the inside of the fluid bag into a plurality of spaces, the capacity corresponding to the partition portion can be reduced from the capacity of the fluid bag.

In the cuff for a blood pressure monitor of one embodiment,
The partition is provided at the center in the direction orthogonal to the width direction of the fluid bag.

According to the above embodiment, when the fluid bag is fixed to the wrist by the fixing means, the partition portion is provided at the center in the direction orthogonal to the width direction of the fluid bag, so that among the plurality of spaces in the fluid bag. One of them can be located on the ulnar artery and the other of the plurality of spaces in the fluid bag can be located on the radial artery. Therefore, the ulnar artery and radial artery can be reliably compressed.

In the cuff for a blood pressure monitor of one embodiment,
The partition portion is provided so as to be closer to one end side than the center in the direction orthogonal to the width direction of the fluid bag.

According to the above embodiment, when the fluid bag is fixed to the wrist by the fixing means, the partition portion is provided so as to be closer to the one end side than the center in the direction orthogonal to the width direction of the fluid bag. One of the plurality of spaces in the bag can be larger than the other one of the plurality of spaces in the fluid bag. Therefore, if a large one of the plurality of spaces in the fluid bag is positioned on the ulnar artery, the ulnar artery at a position deeper than the radial artery can be appropriately compressed.

In the cuff for a blood pressure monitor of one embodiment,
The length of the wide portion in the direction orthogonal to the width direction is not less than 1/2 and not more than 3/4 of the length in the direction orthogonal to the width direction of the fluid bag.

According to the embodiment, when the fluid bag is fixed to the wrist by the fixing means, the length in the direction orthogonal to the width direction of the wide portion is the length in the direction orthogonal to the width direction of the fluid bag. Since it is 1/2 or more and 3/4 or less, it is possible to avoid a situation in which only one of the ulnar artery and radial artery can be compressed.

The cuff for a sphygmomanometer of the present invention includes a fluid bag to which a fluid is supplied in order to compress the artery, and the fluid bag has a wide portion disposed on the artery and the wide portion connected to the wide portion. Since it has the narrow part with a narrow width | variety, the capacity | capacitance of a fluid bag can be reduced.

In addition, since the edge of the narrow part connected to the edge of the wide part has a substantially linear shape that is inclined with respect to the width direction, the wide part and the narrow part have an obtuse angle. It is possible to prevent stress concentration from occurring at the boundary of the narrow portion. Therefore, when a fluid is supplied to the fluid bag, it is possible to make it difficult to break.

The surface of the sphygmomanometer body 2 is provided with a display unit 21 for displaying various information including blood pressure values and an operation unit 22 operated to input various instructions for measurement. Further, although not shown, the output value of the sphygmomanometer body 2 changes depending on the pump that supplies air to the air bag 101 in the sphygmomanometer cuff 3 or the pressure in the air bag 101 (hereinafter referred to as “cuff pressure”). And a control device for controlling the pump and the pressure sensor.

FIG. 2 is a schematic plan view of the sphygmomanometer cuff 3 as viewed from the sphygmomanometer body 2 side. FIG. 3 is a schematic sectional view taken along line III-III in FIG.

As shown in FIGS. 2 and 3, the sphygmomanometer cuff 3 includes an air bag 101 having an octagonal shape in plan view, a cuff belt 102 for fixing the air bag 101 to the wrist W, and a cuff belt 102. And a connecting member 103 for connecting the air bag 101 to the air bag 101. The air bag 101 is an example of a fluid bag, and the cuff belt 102 is an example of a fixing means. In FIG. 2, the vertical direction corresponds to the width direction of the cuff belt 102 and the air bag 101, and the horizontal direction corresponds to the longitudinal direction (direction orthogonal to the width direction) of the cuff belt 102 and the air bag 101. Both ends in the longitudinal direction of the cuff strip 102 are represented by reference numerals 102e and 102f.

The air bag 101 is disposed in a space in the cuff band 102 so as to be closer to the end 102e in the longitudinal direction of the cuff band 102. The air bag 101 has an inner sheet 111 disposed on the wrist W side and an outer sheet 112 disposed on the blood pressure monitor main body 2 side. When air is supplied from the pump to the air bladder 101, the air bladder 101 expands and compresses the radial artery RA and the ulnar artery UA. Such an air bag 101 is obtained, for example, by preparing an inner sheet 111 and an outer sheet 112 having substantially the same shape, and welding the peripheral edge of the inner sheet 111 and the peripheral edge of the outer sheet 112 to each other. As the material of the inner sheet 111 and the outer sheet 112, any material can be used as long as it is rich in elasticity and does not leak from the peripheral edge after welding. Specifically, EVA (ethylene-vinyl acetate copolymer), PVC (soft vinyl chloride), PU (polyurethane), TPE-O (olefin-based thermoplastic elastomer), raw rubber, and the like are used for the inner sheet 111 and the outer sheet 112. It is mentioned as a material.

The cuff strip 102 has an inner cloth 121 facing the inner sheet 111 and an outer cloth 122 facing the outer sheet 112. When the cuff strip 102 is wound around the wrist W, most of the inner cloth 121 is in direct contact with the wrist W. Moreover, the planar view shape of the outer cloth 122 and the inner cloth 121 is substantially rectangular, and the peripheral edge part of the outer cloth 122 and the peripheral edge part of the inner cloth 121 are stitched together. Further, a polyester surface fastener 123 is provided on the outer surface (surface opposite to the air bag 101 side) of the end portion 102f in the longitudinal direction of the inner cloth 121 (direction in which the cuff strip 102 is wound around the wrist W). The material of the outer cloth 122 is, for example, polyester fiber, and the material of the inner cloth 121 is, for example, polyamide or polyurethane fiber.

The connecting member 103 includes a base portion 131 whose peripheral portion is welded to the outer sheet 112, a first tube portion 132 for taking air into and out of the air bag, and a second tube portion 133 for detecting cuff pressure. And a hook portion 134 whose front end portion is locked to the outer cloth 122. The base part 131, the first cylinder part 132, the second cylinder part 133, and the hook part 134 are integrally formed by resin molding. In addition, the first cylinder part 132 and the second cylinder part 133 extend from the base part 131 toward the outer cloth 122 side, and the tip ends project from the outer cloth 122. Similarly to the first cylinder part 132 and the second cylinder part 133, the hook part 134 also extends from the base part 131 toward the outer cloth 122 side, and the tip part protrudes from the outer cloth 122. Is bent into an inverted L shape in side view (see FIG. 5).

FIG. 4 is a schematic plan view of the air bag 101 as viewed from the blood pressure monitor main body 2 side. FIG. 5 is a schematic sectional view taken along line VV in FIG.

As shown in FIGS. 4 and 5, the air bag 101 includes a wide portion 104 disposed on the radial artery RA and the ulnar artery UA, and a longitudinal direction of the wide portion 104 (direction in which the cuff band 102 is wound around the wrist W). ) And the other end in the longitudinal direction of the wide portion 104 (the direction in which the cuff strip 102 is wound around the wrist W). Has a narrow second narrow portion 106. The length L1 of the air bag 101 in the longitudinal direction is set to 140 mm, for example. The first narrow portion 105 and the second narrow portion 106 are examples of narrow portions provided at one end in the longitudinal direction.

The planar view shape of the wide portion 104 is a rectangular shape. The length L2 in the longitudinal direction of the wide portion 104 is set to 100 mm, for example.

If the longitudinal ends of the air bag 101 are denoted by reference numerals 101e and 101f, the first narrow portion 105 is provided at the longitudinal end portion 101f of the air bag 101, while the second narrow portion is provided. The portion 106 is provided at an end 101 e in the longitudinal direction of the air bag 101. The first and second narrow portions 105 and 106 each have a shape in which the width gradually decreases as the distance from the wide portion 104 increases. More specifically, the width W1 of the first narrow portion 105 and the second narrow portion 106 on the wide portion 104 side is set to 60 mm, for example, and the first narrow portion 105 and the second narrow portion 106 on the wide portion 104 side. The width W2 on the opposite side is set to 20 mm, for example. The edges 105a and 106a of the first and second narrow portions 105 and 106 connected to the edge 104a of the wide portion 104 have a linear shape inclined with respect to the width direction. Further, the edges 105b and 106b of the first and second narrow portions 105 and 106 connected to the edge 104b of the wide portion 104 also have a linear shape inclined with respect to the width direction. That is, the planar view shapes of the first and second narrow portions 105 and 106 are shapes obtained by rotating the trapezoid by 90 °.

According to the sphygmomanometer cuff 3 having the above configuration, since the air bag 101 has the first and second narrow portions 105 and 106 that are narrower than the wide portion 104, the capacity of the air bag 101 can be reduced. Therefore, it is possible to reduce the size of the sphygmomanometer 1 and reduce the thickness thereof by reducing the size of the pump.

Further, the edges 105a, 105b, 106a, 106b of the first and second narrow portions 105, 106 connected to the edges 104a, 104b of the wide portion 104 have a linear shape inclined with respect to the width direction. Accordingly, the edge 104a of the wide portion 104 and the edges 105a and 106a of the first and second narrow portions 105 and 106 form an obtuse angle, and the edge 104b of the wide portion 104 and the first and second narrow portions 105, The edges 105b and 106b of 106 form an obtuse angle. Therefore, when air is supplied to the air bag 101, stress concentration is not generated at the boundary between the wide portion 104 and the first and second narrow portions 105 and 106, so that the air bag 101 is not easily broken. be able to.

Further, since the first narrow portion 105 is provided at one end portion in the longitudinal direction of the air bag 101 and the second narrow portion 106 is provided at the other end portion in the longitudinal direction of the air bag 101, the radial artery The wide portion 104 can be securely placed on the RA and the ulnar artery UA to sufficiently compress the radial artery RA and the ulnar artery UA. Therefore, even if the air bag 101 has the first and second narrow portions 105 and 106, the blood pressure measurement accuracy can be improved.

In the above embodiment, the air bag 101 to which air is supplied is used to compress the artery, but a liquid bag to which liquid is supplied to press the artery may be used.

In the above embodiment, the edges 105a, 105b, 106a, 106b of the first and second narrow portions 105, 106 connected to the edges 104a, 104b of the wide portion 104 have a linear shape inclined with respect to the width direction. However, a shape in which a part of a straight line (for example, an end) is curved may be exhibited.

In the above embodiment, an example in which the sphygmomanometer cuff of the present invention is applied to a wrist sphygmomanometer has been described, but the sphygmomanometer to which the sphygmomanometer cuff of the present invention is applied is not limited to a wrist sphygmomanometer. That is, the sphygmomanometer to which the sphygmomanometer cuff of the present invention is applied may be worn anywhere on the human body, such as the upper arm, thigh, ankle or finger.

In the above embodiment, the air bag 101 is covered with the cuff belt so as not to contact the part to be measured, but may be made to contact the part to be measured.

In the above embodiment, the length L2 in the longitudinal direction of the wide portion 104 is preferably not less than 1/2 and not more than 3/4 of the length L1 in the longitudinal direction of the air bag 101. That is, it is desirable to set L2 within the range of 1 / 2L1 to 3 / 4L1. When set in this way, it is possible to avoid a situation in which only one of the ulnar artery UA and the radial artery RA can be compressed.

In the above embodiment, the sphygmomanometer cuff has the air bag 101 shown in FIG. 4, but may have the air bag 201 shown in FIG.

Assuming that both ends of the air bag 201 in the longitudinal direction are denoted by reference numerals 201e and 201f, the air bag 201 has the first narrow portion 105 at the end 201f in the longitudinal direction, like the air bag 101. The second narrow portion 106 is provided at the end 201e in the longitudinal direction. Further, third and fourth narrow portions 207 and 208 are provided at the center portion of the air bag 201 in the longitudinal direction. A first wide portion is provided between the first narrow portion 105 and the third narrow portion 207, and a second wide portion is provided between the second narrow portion 106 and the fourth narrow portion 208. Yes. The first and second wide portions 209 and 210 are wider than the first narrow portion 105, the second narrow portion 106, the third narrow portion 207, and the fourth narrow portion 208. More specifically, the first narrow portion 105 is connected to one end in the longitudinal direction of the first wide portion 209 and gradually becomes narrower as it is away from the first wide portion 209. Further, the second narrow portion 106 is connected to the other end in the longitudinal direction of the second wide portion 210 and gradually becomes narrower as it is separated from the second wide portion 210. Further, the third narrow portion 207 is connected to the other end in the longitudinal direction of the first wide portion 209 and gradually becomes narrower as the distance from the first wide portion 209 increases. Further, the fourth narrow portion 208 is connected to one end in the longitudinal direction of the second wide portion 210 and gradually becomes narrower as it is away from the second wide portion 210. The third and fourth narrow portions 207 and 208 are examples of narrow portions provided in the center portion in the longitudinal direction.

The air bag 201 is obtained by preparing an inner sheet 211 and an outer sheet 212 having substantially the same shape, and welding the peripheral edge of the inner sheet 211 and the peripheral edge of the outer sheet 212 to each other. The material of the inner sheet 211 and the outer sheet 212 is the same as the material of the inner sheet 111 and the outer sheet 112.

Such an air bag 201 can reduce the capacity compared to the air bag 101. In addition, the first wide portion 209 is disposed on the ulnar artery UA and the second wide portion 210 is disposed on the radial artery RA, so that the radial artery RA and the ulnar artery UA can be sufficiently compressed.

Assuming that both end portions in the longitudinal direction of the air bag 301 are represented by reference numerals 301e and 301f, the air bag 301 has the first narrow portion 105 at the end portion 301f in the longitudinal direction, like the air bag 101. The second narrow portion 106 is provided at the end 301e in the longitudinal direction. The air bag 301 has a wide portion 304 between the first narrow portion 105 and the second narrow portion 106. The wide portion 304 is wider than the first and second narrow portions 106. The wide portion 304 is provided with first and second welded portions 341 and 342 that partition the air bag 301 into a plurality of spaces. The first and second welded portions 341 and 342 are located in the center of the air bag 301 in the longitudinal direction, and a predetermined interval is provided between the first welded portion 341 and the second welded portion 342. The space on the first narrow portion 105 side in the air bag 301 and the space on the second narrow portion 106 side in the air bag 301 are interposed between the first welded portion 341 and the second welded portion 342. Communicate. In the first and second welded portions 341 and 342, the length L3 is set to 10 mm, for example, and the width W3 is set to 5 mm, for example. In addition, the 1st, 2nd welding parts 341,342 are an example of a partition part.

The air bag 301 includes an inner sheet 311 and an outer sheet 312 having substantially the same shape, and the peripheral edge of the inner sheet 311 and the peripheral edge of the outer sheet 312 are welded to each other, and the longitudinal direction of the inner sheet 311 is It is obtained by welding a part of the center part and a part of the center part in the longitudinal direction of the outer sheet 312 to each other. The material of the inner sheet 311 and the outer sheet 312 is the same as the material of the inner sheet 111 and the outer sheet 112.

Such an air bag 301 can reduce the capacity compared to the air bag 101. In addition, on the ulnar artery UA, a portion on the first narrow portion 105 side with respect to the first and second welded portions 341 and 342 of the wide portion 304 is disposed, and the wide portion 304 is disposed on the radial artery RA. The radial artery RA and the ulnar artery UA can be sufficiently compressed by disposing the portion on the second narrow portion 106 side with respect to the first and second welded portions 341 and 342.

Further, instead of the first and second welded portions 341 and 342, for example, a block member or a plate member may be used as an example of the partition portion. The block-like member and the plate-like member may be disposed in the air bag 301 and adhered to the inner sheet 311 and the outer sheet 312.

In the above embodiment, the cuff for a blood pressure monitor has the air bag 101 shown in FIG. 4, but may have an air bag 401 shown in FIG.

Assuming that both end portions in the longitudinal direction of the air bag 401 are denoted by reference numerals 401e and 401f, the air bag 401 has the first narrow portion 105 at the end portion 401f in the longitudinal direction, like the air bag 101. The second narrow portion 106 is provided at the end portion 401e in the longitudinal direction. The air bag 401 has a wide portion 404 between the first narrow portion 105 and the second narrow portion 106. The wide portion 404 is wider than the first and second narrow portions 105 and 106. The wide portion 404 is provided with first and second welding portions 441 and 442 that partition the air bag 401 into a plurality of spaces. The first and second welded portions 441 and 442 are closer to the second narrow portion 106 than the center in the longitudinal direction of the air bag 401, and the first and second welded portions are spaced apart by a predetermined interval. 441 and 442 are arranged in the width direction. Further, the space on the first narrow portion 105 side in the air bag 401 and the space on the second narrow portion 106 side in the air bag 401 are interposed between the first welding portion 441 and the second welding portion 442. Communicate. In the first and second welded portions 441 and 442, the length L4 is set to 10 mm, for example, and the width W4 is set to 5 mm, for example. In addition, the 1st, 2nd welding parts 441 and 442 are examples of a partition part.

The air bag 401 includes an inner sheet 411 and an outer sheet 412 having substantially the same shape, and the peripheral edge of the inner sheet 411 and the peripheral edge of the outer sheet 412 are welded to each other. It is obtained by welding a part on the one end side with respect to the center part and a part on the one end part side with respect to the center part in the longitudinal direction of the outer sheet 412. The material of the inner sheet 411 and the outer sheet 412 is the same as the material of the inner sheet 111 and the outer sheet 112.

Such an air bag 401 can reduce the capacity compared to the air bag 101. In addition, on the ulnar artery UA, a portion on the first narrow portion 105 side with respect to the first and second welded portions 441 and 442 of the wide portion 404 is disposed, and the wide portion 404 is disposed on the radial artery RA. By disposing the portion on the second narrow portion 106 side with respect to the first and second welded portions 441 and 442, the radial artery RA and the ulnar artery UA can be sufficiently compressed.

Further, the portion on the second narrow portion 106 side with respect to the first and second weld portions of the wide portion 404 is more than the portion on the first narrow portion 105 side with respect to the first and second weld portions of the wide portion 404. However, since the capacity is large, the ulnar artery UA located deeper than the radial artery RA can be appropriately compressed.

Further, instead of the first and second welded portions 441 and 442, for example, a block member or a plate member may be used as an example of the partition portion. The block-like member and the plate-like member may be disposed in the air bag 401 and bonded to the inner sheet 411 and the outer sheet 412.

6 to 8, the same components as those in FIG. 4 are denoted by the same reference numerals as those in FIG.

Further, a connection member similar to the connection member 103 may be attached to the air bags 201, 301, 401.

Moreover, although the said embodiment and its modified embodiment demonstrated the case where the wrist type | mold blood pressure meter 1 and its modification were mounted | worn to the wrist W of the left hand, the wrist type | mold blood pressure meter 1 and its modification example were demonstrated. Even when worn on the wrist of the right hand, the same effects as those described above can be obtained.
